Polk Streetscape Project

Sign Up for email updates about The Polk Streetscape Project!


Polk Street is a thriving neighborhood and commercial corridor that serves an important transportation function for San Francisco. It also has some of the highest pedestrian and bicycle collision rates in the City. On average, one person walking and one person biking are hit by a vehicle each month on Polk Street (122 in a five-year period).

For years, Polk Street has been the site of many traffic-related injuries and the corridor is currently on San Francisco’s Vision Zero High Injury Network. This network represents 12 percent of San Francisco’s surface streets and is where injuries, including severe and fatal injuries, are most concentrated.

San Francisco's Vision Zero policy calls for eliminating traffic-related fatalities by 2024.

The corridor is not only the designated street for the #No. 19 Muni bus line; it also is a preferred north-south bicycle route due to its flatter terrain. Polk Street also is a popular place for people to walk.

The Polk Streetscape Project was designed to enable safe access for all road users of all ages and abilities. Through community input and technical evaluation, the proposed design includes corridor-wide safety improvements and additional streetscape amenities at key locations.

Partnering on the project are San Francisco Public Works, San Francisco Planning Department, the San Francisco Municipal Transportation Agency and the San Francisco Public Utilities Commission.

The Polk Streetscape Project aims to increase safety for people walking and biking on Polk Street, as well as improve the efficiency of transit on the corridor. This project will build on Polk Street's vibrant commercial character by improving safety and transportation choices.

Upcoming improvements on Polk Street between Beach and McAllister streets and nearby alleyways will include repaving, street base repair, sidewalk corner bulb-outs, to shorten the crossing distance, ADA-compliant curb ramp upgrades, Muni bus stop optimization; such as bus stop consolidation or relocation, bus bulb-outs for easier boarding, and left and right turn lanes to improve traffic flow, raised cycle tracks, green bike lanes, sewer replacements, water line replacement, traffic signal upgrades, high visibility crosswalks, better visibility at crosswalks, commercial-loading improvements, landscaping, tree planting, street lighting and alley enhancements to Fern Alley, to enhance the pedestrian and biscyclist experience with the creation of a well-lit plaza atmosphere, widening of the existing sidewalk, decorative asphalt, raised crosswalks, traffic calming measures and planting of palm trees.

To help achieve these improvements, the design necessitates the removal of 106 parking spaces along the Polk Street corridor and 28 spaces on side streets.

Updates on changes of design elements on the Polk Streetscape Project:

SFMTA has recently announced that plans for Polk Street bike lane will be modified from raised to road level.
The previous plan for the Polk Streetscape Project included a raised bike lane, with a two-inch mountable curb, on the northbound side of Polk from McAllister to Pine streets. But in our experiment with different curb designs last year on Market Street, we found that raised bike lanes on commercial streets like Polk should have a parking-protected configuration, with a lane of car parking and loading zones between the bike lane and the roadway, to prevent drivers from parking in the bikeway.
Making room for that parking lane on Polk would require major changes to the plan already under construction. To make the bike lane safer without a major delay, the northbound bike lane will no longer be raised but will be built at road level with plastic safe-hit posts and a painted buffer zone to separate it from the traffic lanes.
For more information, visit
Crosswalk design at Polk and Green streets will be modified to reflect SFMTA crosswalk guidelines and to meet budget constraints.
Crosswalks along Polk Street are marked using continental striping. The SFMTA adopted continental crosswalk striping as the citywide standard in May 2014. The proposed decorative crosswalk shown at Polk and Green by the City in March 2014 during the community outreach phase of the project will not be used. The high visibility continental crosswalk markings help advance our goal to make Polk Street safer for everyone. We apologize for not notifying the community sooner. 
Please be assured that other key safety improvements will be implemented along Polk Street. The City is building on Polk Street's vibrant commercial character by investing in new lighting, landscaping, repaving, installation of a protected bike lane, sidewalk bulb-outs, traffic signal upgrades, pedestrian countdown signals and ADA curb ramp upgrades.
